. 1 Be it known that I, JOSEPH N. BORGLIN, a

citizenof the United States, residing at Seattle, in" the. county of King :and State :of Washington, have invented certain new and usefulwImprovements in Ship-Launching Devices, 1 of which thefollowing 1s. a;

specification. r

This invention relates tomeans for launching a ship. 1 E i I While building a ship, it. isworked up finished and .is to be launched, longitudinal beams areapiled on ways each side the supports, andwedges aredrlven in between the beams to remove the weight from the sup ports so that the hull may slide of its own *wei'ght into the water. j The wedges have heretofore been-driven in manually and this old method is necessarily slow and expensive. According to this invention it is proposed to provide a portable power hammer CllS- posed adjacent the sides of a vessel on'the 1 ways, and when the hull is to be launched the hammer is moved into position to strike suc- The invention also comprehends improvements in the details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the claims.

a In the drawings:.

"Figure 1 is an end view conventionally illustrating a ship on the ways, and my i mproved wedge driving means in operative position.

Fig-2 is a plan View of the same.

Fig. 3 is a side view of the hammer operating mechanism.

Fig. 4 is a detail cross section of the top of-the truck.

Fig. 5 is a detail longitudlnal section of the same.

Fig. 6 is a detail view of the hammer.

1 indicates a central fixed support of a ships way composed of beams piled one on the other, and 2 a hull supported thereon. On each side of the supportis a slide 3, which, when the ship is launched is greased, and which is provided with guides 4;. Filed on Specification of Iietters Patent.

posed between the beams 5,-at suitable in tervals, are Wedges 6, all ofusualconstruction and arrangement. 1

Alongsidethe slides, and suitably spaced 8, carrying the hammers and, the operating mechanism therefor. As i the mechanism supported on the trucks is identical, butone willbe described. 1

which .is provided with toothed gibsflQ, opcrating. 1n guideways 11, in thetruck-drame.

-' A shaft 12, extends longitudinally through the truck, and has fixed theretmpinion's-m, which mesh with the rack teeth on the gibs.

: The ishaft is also provided-with 3a @hjmfdle 14:, aratchet wheel 15, and a pawl 16, cooperating with the ratchet to hold the parts in adjusted position.

Extending from the platform 9, are standards 17, which support a table 18, having guideways 19. Mounted in bearings in a pair of the standards 17 is a crank shaft 20, provided on one end with a fly wheel 21, and on its opposite end with a gear wheel 22.

The crank shaft 20 cooperates with a hammer 23, provided with side flanges 24, which operate in the guideways 19, and on one end of the hammer is a lug 25, disposed in the path of the crank 0f the shaft 20. One end of a spring 26, is connected to the rear end of the hammer, and the opposite end of said spring is attached to the table, the tension of the spring being such as to withdraw'the hammer after the crank has driven it in the opposite direction.

. A suitable motor 30, is mounted on the platform to drive the crank shaft. The motor comprises a base 31, crank shaft 32, cyleo nteet w ifih the 25,:and the Springs are placed under tension.
